Beni culturali e sviluppo, territorio e turismo.
2008
Il lavoro di valorizzazione del patrimonio culturale è considerato dalla pianificazione urbanistica di scuola cosiddetta “territorialista” fattore catalizzante nella generazione di processi di sviluppo locale “auto-sostenibili”. Le ragioni sono molteplici e il richiamarle è utile a motivare il radicamento in una facoltà di architettura di una formazione specialistica per tale lavoro, condotta in forma di ricerca esperienziale in ambiente interdisciplinare, applicando metodologie di costruzione di itinerari tematici dell’arte e dell’architettura.
Formaldehyde and total aldehydes in indoor air of public environments by voltammetry
2014
The proposed method involves active sampling, where a sampling pump is used to pull air through a solution and voltammetric analysis of the obtained solutions. No interferences have been observed. In addition, very little sample preparation is required. Analyses were performed in 19 indoor stations and one in outdoor. Measurements were carried out on University environments: Museum of Chemistry, Zoological Museum, libraries, laboratories, corridors, meeting rooms, photocopying room, machine shop and terrace. Formaldehyde concentrations in analyzed samples ranged from 2.6 to 85 μg m-3 (median = 32 μg m-3), while the sum of others aldehydes ranged from 2 to 25 μg m-3 (median =2.4 μg m-3). In …
Micro-determination of dithiocarbamates in pesticide formulations using voltammetry
2013
Abstract The purpose of this work was to develop a reliable method for the micro-determination of dithiocarbamates (mancozeb, maneb, propineb, nabam, Na(CH3)2DTC, zineb, ziram, ferbam and thiram) in pesticide formulations for agriculture using adsorptive stripping voltammetry (AdSV). The accuracy of analytical method was valued by analyzing simulate formulation samples prepared by us with known amounts of active ingredients. In addition, the applicability of the AdSV procedure for the analysis of DTCs and EBDTCs in micro-samples was evaluated by estimating its recoveries from spiked commercial formulate samples. The accuracy, valuated as recovery percentage ranged between 85% and 97%. The p…
Gli affreschi provenienti dalle terme romane di Reggio Calabria. Dalla conoscenza al restauro
2023
The frescoes at marine thermae discovered in 1886 during the excavation of the small thermal complex dating between the 1th and 3rd century AD, and located on the seafront of Reggio Calabria, have been collected already collapsed. They are currently part of the permanent exhibition of the National Archaeological Museum of Reggio Calabria. This paper illustrates the results of the restoration intervention, carried out in the form of an educational activity in the context of an agreement signed between the MarRC and the University of Calabria, and the results of the diagnostic investigations carried out by the IPCF-CNR of Messina and the STEBICEF department of the University of Palermo.
Composition and corrosion phases of Etruscan Bronzes from Villanovan Age
2008
A neutron diffraction (ND) and neutron tomography (NT) study of laminated ancient bronzes was performed at the ISIS (Rutherford Appleton Laboratory, UK) neutron source and at the BENSC reactor (Hahn-Meitner Institut, Germany). The samples are part of an 8th century BC Etruscan collection discovered in the necropolises of Osteria-Poggio Mengarelli and Cavalupo in the Vulci area (Viterbo, Italy). The study allowed us to derive-in a totally non-destructive manner-information related to the main composition of the objects, possible presence of alterations and their nature, crusts and inclusions, as well as structure of the bulk. The presence of some components is linked to a variety of question…
Statistical Approximation of Fourier Transform-IR Spectroscopy Data for Zinc White Pigment from Twentieth-Century Russian Paintings
2017
We present a statistical model for approximation of experimental Fourier transform-IR spectroscopy (FTIR) data for paint samples from paintings of different ages. The model utilizes random variations in some parameters (initial ageing rate, degree of change in ageing rate and time at which the change occurs). We determine the parameters characterizing variation in the paint composition and the storage conditions for the paintings. The numerical calculation is qualitatively consistent with the experimental data. In the proposed model, changes in the initial composition of the paint and the storage conditions make about the same contribution to the experimentally observed scatter in the data …
High frequency data entry: statistical findings at high frequency
2010
We introduce some of the most common types of high-frequency financial data: tick-by-tick data, trade andquote data, order bookdata, andmarket member data. We describe the types of variables that are usually available in the most popular high-frequency financial databases. We discuss the issues related to the handling of these data, including cleaning protocols, timing issues, and issues related to data size. We then briefly consider the issues related to the stylized facts detected in the empirical analysis of high- frequency data. Specifically, we consider (i) the irregular temporal spacing of the events at high frequency and its relevance for the econometric modeling of financial variables, (…
